Content overview: “Rosetta Spacecraft’s Historic Comet Selfie: Why This 2014 Photo Still Inspires”. The Astronomy Picture of the Day for October 24, 2026, revisits a landmark image from the European Space Agency’s Rosetta mission: a selfie taken by the spacecraft in 2014, showing its own solar panels with comet 67P/Churyumov–Gerasimenko looming in the background. The photograph, captured by the Philae lander’s CIVA camera shortly after separating from Rosetta, marked the first time a spacecraft had ever soft-landed on a comet. The image became an icon of space exploration, demonstrating the feasibility of rendezvousing with and studying these ancient icy bodies up close.
Rosetta orbited the comet for over two years, tracking its activity as it approached the Sun, while Philae’s brief but historic touchdown provided the first direct measurements from a comet’s surface. The mission’s success reshaped planetary science, revealing that comets contain complex organic molecules and may have delivered water to early Earth.
